CONST_DISFFCFLAGS

Members of the CONST_DISFFCFLAGS enumeration are used to specify the command sent by using the DirectInputDevice.SendForceFeedbackCommand method.

Enum CONST_DISFFCFLAGS
    DISFFC_CONTINUE =         8 
    DISFFC_PAUSE =            4 
    DISFFC_RESET =            1 
    DISFFC_SETACTUATORSOFF = 32 (&H20)
    DISFFC_SETACTUATORSON =  16 (&H10)
    DISFFC_STOPALL =          2 
End Enum
DISFFC_CONTINUE
Paused playback of all active effects is to be continued. It is an error to send this command when the device is not in a paused state.
DISFFC_PAUSE
Playback of all active effects is to be paused. This command also stops the clock on effects, so that they continue playing to their full duration when restarted.

While the device is paused, new effects may not be started and existing ones may not be modified. Doing so may result in the subsequent DISFFC_CONTINUE command failing to perform properly.

To abandon a pause and stop all effects, use the DISFFC_STOPALL or DISFCC_RESET commands.

DISFFC_RESET
The device's force-feedback system is to be put in its startup state. All effects are removed from the device, are no longer valid, and must be recreated if they are to be used again. The device's actuators are disabled.
DISFFC_SETACTUATORSOFF
The device's force-feedback actuators are to be disabled. While the actuators are off, effects continue to play but are ignored by the device. Using the analogy of a sound playback device, they are muted rather than paused.
DISFFC_SETACTUATORSON
The device's force-feedback actuators are to be enabled.
DISFFC_STOPALL
Playback of any active effects is to be stopped. All active effects will be reset, but are still being maintained by the device and are still valid. If the device is in a paused state, that state is lost.

This command is equivalent to calling the DirectInputEffect.Stop method for each effect playing.
